Aim. Estimation of the liver steatosis and fibrosis incidence with transient elastography and the controlled attenuation parameter in residents of St. Petersburg.Materials and methods. A prospective open single-centre population study included history, anthropometric and laboratory data on 318 outpatients aged 24—89 years (mean age 52.6 ± 14.6 years). The degrees of steatosis (assessed with the controlled attenuation parameter as ultrasound amplitude dropdown quantification in liver) and fibrosis were determined with a Fibroscan 502 Touch unit (Echosens, France).Results. Hepatic steatosis of predominantly high degree was revealed in 44.7%, combined fibrosis and steatosis — in 28%; isolated fibrosis of various stage — in 2.5%, no structural changes — in 24.8% individuals. The growth of body mass index and waist circumference significantly correlated in women with pronounced liver changes. Serum transaminase activity increased with more severe liver changes, being statistically significant for aspartic transaminase only.Conclusion. A high incidence of primary liver steatosis and fibrosis in residents of St. Petersburg warrants improved diagnostic algorithms and routine preventive measures. Transient elastography with the controlled attenuation parameter estimation provides a convenient non-invasive screening for hepatic fibrosis and steatosis.

A Prospective Study

Background & Aims: A novel non-invasive tool based on the evaluation of ultrasound attenuation using transient elastography (TE) has been developed, called controlled attenuation parameter (CAP). We aim to establish the histopathological parameters that significantly influence CAP, the cutoff values and their performance in predicting each steatosis grade on a group of biopsied patients with chronic liver diseases (CLD) from Romania.Methods. We prospectively analyzed 201 consecutive CLD patients who underwent CAP measurements using TE. Steatosis, liver fibrosis and necroinflammatory activity were staged and graded during the pathological analysis of bioptic specimens. Univariate and multivariate regression analyses were applied to identify the variables correlated with CAP values. The diagnostic performance of CAP for steatosis prediction was assessed using an AUC analysis.Results. Among the histopathological factors correlating with CAP, the multivariate analysis found steatosis as the only factor independently influencing CAP values (p<0.001). Maximal diagnostic accuracy (DA) was obtained for the prediction of ≥34-66% (S2) fatty load and of 67-100% (S3) fatty load (82.06%, respectively 81.59%) while, for the prediction of ≥11-33% (S1) fatty load, DA reached only 76.11%. The negative predictive value for the exclusion of ≥S2 and S3 was 93.5% and 98.7%, respectively. AUCs calculated between each two steatosis grades were: 0.772 (S0 vs S1), 0.874 (S0 vs S2), 0.904 (S0 vs S3), 0.659 (S1vs S2), 0.777 (S1 vs S3), and 0.665 (S2 vs S3).Conclusion. Steatosis is the only histopathological factor independently influencing CAP. Maximal DA could be obtained for the prediction of ≥S2 and S3 (82.06% and 81.59%), while for the prediction of S1, the accuracy reached only 76.11%.

Background: Type 2 diabetes mellitus (T2DM), obesity, hyperlipidemia, and hypertension are considered risk factors for developing non-alcoholic fatty liver disease (NAFLD). This study aims to assess steatosis and fibrosis severity in a cohort of T2DM patients, using vibration controlled transient elastography (VCTE) and controlled attenuation parameter (CAP). Material and method: We performed a prospective study in which, in each patient, we aimed for 10 valid CAP and liver stiffness measurements (LSM). To discriminate between fibrosis stages, we used the following VCTE cut-offs: F ≥ 2–8.2 kPa, F ≥ 3–9.7 kPa, and F4 - 13.6 kPa. To discriminate between steatosis stages, we used the following CAP cut-offs: S1 (mild) – 274 dB/m, S2 (moderate) – 290dB/m, S3 (severe) – 302dB/m. Results: During the study period, we screened 776 patients; 60.3% had severe steatosis, while 19.4% had advanced fibrosis. Female gender, BMI, waist circumference, elevated levels of AST, total cholesterol, triglycerides, blood glucose, and high LSM were associated with severe steatosis (all p-value < 0.05). BMI, waist circumference, elevated levels of AST, HbA1c, and CAP were associated with advanced fibrosis (all p-values < 0.05). Conclusion: Higher BMI (obesity) comprises a higher risk of developing severe steatosis and fibrosis. Individualized screening strategies should be established for NAFLD according to different BMI.

<b>Objective:</b> Type 2 diabetes mellitus (T2DM) is an important risk factor for the progression of metabolic liver disease to advanced fibrosis. Here, we provide an estimate of the prevalence of steatosis and fibrosis in US adults with T2DM based on transient elastography (TE) and identify factors associated with these conditions. <p><b>Research Design and Methods: </b>This is a cross-sectional study of US adults with T2DM participating in the 2017-2018 cycle of the National Health and Nutrition Examination Survey who were evaluated by TE. Hepatic steatosis and fibrosis were diagnosed by the median value of Controlled Attenuation Parameter (CAP) and Liver Stiffness Measurement (LSM), respectively.</p> <p><b>Results:</b> Among the 825 patients with reliable TE exams, 484 (53.7%) were assessed using the M probe and 341 (46.3%) using the XL probe. Liver steatosis (CAP≥274 dB/m), advanced fibrosis (LSM≥9.7 Kpa) and cirrhosis (LSM≥13.6 Kpa) were present in 73.8% (95% CI 68.5%-78.5%), 15.4% (95% CI 12.2%-19.0%) and 7.7% (95% CI 4.8%-11.9%) of patients, respectively. Mean age of patients with advanced fibrosis and cirrhosis was 63.7 ± 2.2 years and 57.8 ± 1.6 years, respectively. In the multivariable logistic regression model, body mass index (BMI), non-African American ethnicity and alanine aminotransferase levels were independent predictors of steatosis, while BMI, non-African American ethnicity, aspartate aminotransferase and gamma-glutamyltranspeptidase levels were independent predictors of advanced fibrosis.</p> <p><b>Conclusions:</b> Prevalence of both liver steatosis and fibrosis are high in patients with T2DM from the US and obesity is a major risk factor. Our results support the screening of these conditions among diabetic patients.</p>

Vibration-Controlled Transient Elastography (VCTE) with Controlled Attenuation Parameter (CAP) is used as a non-invasive method for evaluating liver steatosis and fibrosis simultaneously. In this prospective study, we aimed to assess the prevalence of liver steatosis and fibrosis, as well as the associated risk factors in Romanian medical students by VCTE and CAP score. We used a cut-off CAP score of ≥248 dB/m for the diagnosis of mild steatosis (S1), ≥268 dB/m for moderate steatosis (S2), and ≥280 dB/m to identify severe steatosis (S3). For liver fibrosis, the cut-off values were: ≤5.5 kPa, indicating no fibrosis (F0), 5.6 kPa for mild fibrosis (F1), 7.2 kPa for significant fibrosis (F2), 9.5 kPa for advanced fibrosis (F3), and 12.5 kPa for cirrhosis (F4). In total, 426 Romanian medical students (67.8% females, mean age of 22.22 ± 1.7 years) were evaluated. Among them, 352 (82.6%) had no steatosis (S0), 32 (7.5%) had mild steatosis (S1), 13 (3.1%) had a moderate degree of steatosis (S2), and 29 (6.8%) had severe steatosis (S3). Based on liver stiffness measurements (LSM), 277 (65%) medical students did not have any fibrosis (F0), 136 (31.9%) had mild fibrosis (F1), 10 (2.4%) participants were identified with significant fibrosis (F2), 3 (0.7%) with advanced fibrosis (F3), and none with cirrhosis (F4). In conclusion, the prevalence of liver steatosis and fibrosis is low among Romanian medical students.
